Blood type can be tested by drawing blood from the hospital. There are two blood group systems commonly used in clinic, ABO blood group system and RH blood group system. The type of bleeding can be checked by laboratory test, and the operation is relatively simple. As long as the peripheral venous blood is drawn, it can be tested, and the results can be obtained in 20 minutes.
There are four most common blood types in blood group classification, namely: type A blood, type B blood, type AB blood, type O blood and RhD positive blood. RhD negative blood is the rarest blood type. There are dozens of blood typing systems, and the two main typing systems are ABO blood type and Rh blood type. At present, it is used for clinical blood group identification and transfusion of blood products.
